How to augment cosmic shear measurements with radio polarimetry of galaxies?
Liang Dai, Junwu Huang, Weichen Winston Yin +2
The integral polarization of spiral galaxies in the radio band has been proposed as a new tracer of the intrinsic galaxy shape that augments lensing shear measurements. We revisit…
Constraints on axions from patchy screening of the cosmic microwave background
Samuel Goldstein, Fiona McCarthy, Cristina Mondino +3
The resonant conversion of cosmic microwave background (CMB) photons into axions within large-scale structure induces an anisotropic spectral distortion in CMB temperature maps. Ap…
A New Probe of Cosmic Birefringence Using Galaxy Polarization and Shapes
Weichen Winston Yin, Liang Dai, Junwu Huang +2
We propose a novel statistical method to measure cosmic birefringence and demonstrate its power in probing parity violation due to axions. Exploiting an empirical correlation betwe…
